The chemodosimetric behavior of dichlorofluorescein derivatives toward Hg(2+) ions was investigated. Simple chemodosimetric systems showed selective and efficient signaling behaviors toward micromolar concentrations of Hg(2+) ions over other common interfering metal ions in an aqueous environment. The signaling mechanism is selective mercuration of the 4',5'-position of the xanthene moiety, which results in efficient chromogenic and fluorogenic signaling of Hg(2+) ions in aqueous environment.
研究了二氯荧光素衍生物对Hg(2+)离子的化学计量行为。简单的化学计量系统在水性环境中对微摩尔浓度的Hg(2+)离子表现出选择性和高效的信号行为，相对于其他常见的干扰金属离子而言。信号传导机制是呫吨部分4',5'-位的选择性汞化，这导致Hg(2+)离子在水性环境中产生高效的显色和荧光信号。
